Differences Between Change Log Capacity in CDO and Size of an Exported Change Log

The information that you export from CDO's Change Log page is different from the change log information that CDO stores in its database.

For every change log, CDO stores two copies of the device's configuration–the starting configuration and either the ending configuration in the case of a closed change log or the current configuration in the case of an open change log. This allows CDO to display configuration differences side by side. In addition, CDO tracks and stores every step (change event) with the username that made the change, the time the change was made, and other details.

However, when you export the change log, the export does not include the two complete copies of the configuration. It only includes the change events, which makes the export file much smaller than the change log that CDO stores.

CDO stores change log information for a year. This includes two copies of the configuration.
